I want to use either RC or RL and design a band pass and band stop filters.

How can I do that ?

value of capacitor and resistors are as chosen as per requirement of pass band.

This kind of information is not enough.
Active or passive?
Which order?
Both characteristics at the same time (from the same multi-opamp circuit with two outputs)?

Passive implementation is restricted to cascaded first order high and low passes, no complex pole pairs resepectively higher filter Q are available.

...if the design is restricted to RC or RL elements only (RCL allows complex poles).

Question: Which frequency range?

Take any frequency range of your choice.

Are you really asking for any bandpass with any center frequency?

Didn't you hear up to now about a simple resonant (tank) circuit?
Didn`t you find no relevant information in the WEB?

For my opinion, this forum is good for answering specific questions targeting to some challenging problems - but asking for a simple
bandpass topology without any specific requirements.....?

Tank circuit uses R,L and C. I want to use either RL or RC but not both.

In this case, read FvM's reply #6 and spent 1 minute to search in the WEB.

It's been said, that you can implement passive RC (or RL) band pass and band stop filters. So what you are asking in detail? You'll need at least a specification.

The circuit posted by uday mehta should be slightly modfied to achieve a band stop filter, the most simple band pass is a RC low pass / RC high pass cascade (both orders possible).
